Xorg.0.log (xf86-video-intel-2.3.0 driver)

Overview:

  Sometimes at viewing video with mplayer it is visible two frames simultaneously.

  I.e. sometimes the picture looks as follows:

111111111111111111111111111
111111111111111111111111111
111111111111111111111111111
111111112222222222222222222
222222222222222222222222222
222222222222222222222222222
222222222222222222222222222
222222222222222222222222222
222222222222222222222222222

  "1" - part of some frame
  "2" - part of next frame

  This bug it is well visible at viewing video with a high level of movement.

  Affected all versions of xf86-video-intel what I tested: 2.1.1, 2.2.1, 2.3.0
  Not affected all versions of xf86-video-i810 what I tested: 1.6.5, 1.7.4

Steps to reproduce:

  Get Dell Latitude X1 laptop
  Install FreeBSD 6.3
  Install Xorg with xf86-video-intel driver from ports
  Install mplayer from ports
  Run Xorg, start to play some video with high level of motion with mplayer
  Switch to full screen (press "f" key)
  Closely look at screen - you should see described bug

  Compare with xf86-video-i810 driver - in this case the bug should be absent
